ADTPro is a feature-rich communications platform for exchanging disks and disk images between the Apple 8-bit family computers and the modern world. ADTPro has two main purposes in life: transferring Apple disk images, and bootstrapping Apple II computers when boot diskettes are long gone. ADTPro uses any of three communications mechanisms: serial (RS-232, USB) hardware, A2Retrosystems "Uthernet" ethernet card, Audio/Cassette ports, bootstrapping chores can occur with zero software at the Apple II end over serial and audio communications links. Extensive help and tutorials are available on the ADTPro website.

- Server and client agree on more situations where a transfer should be aborted
- [Client] Don't hang on a GS on startup if a connection isn't pre-established
- [Server] Flush the serial send buffer occasionally for our native serial port friends
